The average Earth-Moon distance is 3.84 X 10^5 km, while the Earth-Sun is 1.496 X 10^8 km. Since the radius of the Moon is 1.74 X 10^3 km and that of the Sun is 6.96 X 10^5 km. a) Calculate the angular radius of the Moon and the Sun, qmax, according to the following figure. D Bax R b) Calculate the solid angle of the Moon and the Sun as seen from Earth. (c) Interpret its results; Would this be enough to explain the occurrence of total solar eclipses?
Thank you for the explanation, but this didn't answer my question. I need to know the angles for qeustion 2, 3, and 4. With explanations on how to get them.
Suppose, we recently discovered a new planet named Concordia. If for 15 degrees difference, the distance between Cansae City and and Cantabrigia City would have been 6050 stadia. According to Erasthosthenes' calculation, what would have been the circumference of Concordia? 5.45E5 stadia 2.45E5 stadia 4.45E5 stadia 1.45E5 stadia 3.45E5 stadia
